Making best webcam even better

I have been planing to release Logitech BRIO 4K Pro webcam aluminium unibody rework kit for a while and as soon as I got time, designed and ordered a prototype. After receiving manufactured parts found few minor overlooked issues, but all has been fixed now. Can’t believe how small and slim it is compared to Logitech C920. And now it is ready for small production run.


Brio has USB-C connector soldered straight into PCB, so rework procedure is much simpler than C920. Almost no soldering is required, except for nasty bright white LED which is located near sensor and shines directly into it.

After dissecting fresh Brio you will end up with some left over parts: shell, lens, screws, microphone dampeners, thermal gaskets and few other bits. Silicone thermal gaskets will be reused though, so don’t throw them out.

Brio also has few auxiliary sensors: microphones, IR LED and IR sensor. Microphones will be used with new aluminium kit, so keep them. Infrared emitter and camera will not be used.

Infrared functionality was intended to be used in facial recognition applications and does not affect main camera functionality. And yes, I double and triple checked that camera has no glitches without these IR parts.

Enclosure has standard 1/4″ tripod and multiple other mount features. Also there is plenty of space to add optical filter between sensor and CS-mount or C-mount lens, so besides standard use it can be used in various scientific and computer vision applications.

For your pleasure here is sample picture taken with 2.8-12mm lens. Look at these vibrant colors and crisp sharp picture!

I believe you can do this with DSLR, but can your webcam do this?

    The original Brio has three selections of FOVs. Does that mean there are three lens included in the original Brio?

      Hi, JunHorng. I guess it is horizontal, vertical and diagonal FOV.

        Hi Saulius, Form the document ( ), the Brio 4k has three 65, 78 ,90 degrees of FOV. I just think it should have three sets of lens to provide these sets of FOV. Have you found them when you disassembled it?
        • saulius
          Oh, that's marketing BS, with 4K sensor you can have better crop and have digital zoom.
    Do you mean the 65-FOV image is cropped and interpolated from 90-FOV image?

    Very interested in using the Brio housing. May I ask a few questions? 1) What is the size of the sensor on Brio? 2) Based on the housing design, will the sensor be 12.5mm from the lenses? 3) If the finished product is fixed mounted (set and forget) and considering the electrical modifications required, will Brio have any startup issues when powered up for each session? 4) If I order 3-4 of them, what is the current delivery schedule to US using modestly priced shipping? Cheers, David Lyle

      Hi David, 1. Brio sensor size is about 1/4" 2. Exactly. Distance to sensor is 12.5mm 3. Only two electrical modifications required are: de-soldering lens tabs, removing LED. Brio functions and behaves like original one except from IR secondary camera. 4. UPS usually delivers in a few work days. -- Saulius

    Can you comment which lenses to buy for a beginner? I am interested in the kit and have two use cases in mind: 1) Still use the camera as a webcam. 2) Oculus Mixed Reality, where you capture a person playing with an Oculus Rift and then compositing the person into the 3D-Scene. This needs capturing a person in a square of approx 3m x 3m.

      Hi Axeljaeger, I suggest starting with 2.8-12mm CS mount lens
